HSP用 定義

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。

; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)
; SP_SELECTDEVICE_PARAMS_A サイズ: 612 バイト(x64)
dim st, 153    ; 4byte整数×153(構造体サイズ 612 / 4 切り上げ)
; ClassInstallHeader : SP_CLASSINSTALL_HEADER (+0, 8byte)  varptr(st)+0 を基点に操作(8byte:入れ子/配列)
; Title : CHAR (+8, 60byte)  varptr(st)+8 を基点に操作(60byte:入れ子/配列)
; Instructions : CHAR (+68, 256byte)  varptr(st)+68 を基点に操作(256byte:入れ子/配列)
; ListLabel : CHAR (+324, 30byte)  varptr(st)+324 を基点に操作(30byte:入れ子/配列)
; SubTitle : CHAR (+354, 256byte)  varptr(st)+354 を基点に操作(256byte:入れ子/配列)
; Reserved : BYTE (+610, 2byte)  varptr(st)+610 を基点に操作(2byte:入れ子/配列)
; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。
; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
; ※GUID・入れ子構造体はデフォルト型でないため、依存する #defstruct を先に定義(下記に同梱)。
